- ELECTRIC BELT.

SPECIFICATION forming part of Letters Patent No. 452,250, dated May 12,1891.

Application filed January 17, 1891. Serial No. 378,134=. (N0 model.)

To all whom it may concern.-

Be it known that I, CHARLES D. WILLIAMS, a citizen of the United Statesof America, residing at Silver Lake, in the county of Shawnee and Stateof Kansas, have invented certain new and useful Improvements in ElectricBelts; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had tothe accompanying drawings, and to letters or figures ofreference marked thereon, which form a part of this specification.

This invention relates to improvements in electric or voltaic belts,such as are employed to generate a voltaic current; and it consists inthe construction and combination of the parts, as will be hereinafterfully set forth and particularly claimed.

In the accompanying drawings, forming part of this specification, Figure1 is a perspective View of a voltaic or electric belt constructed inaccordance with my invention. Fig. 2 is a side view showing the severalcells constituting the battery detached. Fig. 3 is a transversesectional view of one of the cells. Fig. 4 is a detail perspective viewshowing the electrodes used at the back of the belt or adjacent to thebattery. Fig. 5 is a front View of the connection used for attaching thebatteries or cells to the supporting-belt.

A refers to the belt, which is made up of webbing and is provided at oneend with a buckle A, which engages with a ring secured to the oppositeend, the buckle used being adjustable upon the belt. The belt carries infront a slide A to which is attached one of the electrodes 0, saidelectrode being connected by a conducting-wire c to the copper elementof the battery.

B refers to the slides upon the back of the belt, each of which hasprojections b and Z) with headed pins b serving to retain in place avertically-adjustable plate B, having a slot 1), reduced at its upperand lower ends, as shown, the upper reduced end being of greater lengththan the lower one. Connected to this adjustable plate by a pin andwasher is a loop B extending from and attached to the case carrying thecells. The loop is connected removably to the cell-case by means of acatch-pin b", one portion of which passes through the eye of the loopwhile the other portion-is without the same and is provided at its endwith a hook which catches the point below the lower eye. By thusconnectingthe cell-case to the belt it can be readily detached for thepurposeof charging the cells, or adjusted upon the slides B, so as tooccupya position adjoining the belt, as shown in Fig. 1, or below thesame, as shown in Fig. 5. An electrode Z projects from a slide D uponthe rear portion of the belt, being connected to said slide by a loopedwire D, which is passed Over the threaded pin d and is permitted toslide thereon or swing in a circle to adjust it to the desired position.The zinc element of the battery is connected to this electrode by thewire .2 being hooked to the loop (1 E refers to the cell-case, which iscomposed of the flap E and body portion or pockets E said pockets beingformed by doubling the material upon itself and stitching, as shown. Theflap E immediately above the cell-pock ets is provided with perforationse, through which pass the conducting-wires attached to the zinc elementsof the cells. This cell-case is made up of water-proof material.

The cells are made up of outer plates F of copper, bent to form acylinder, the ends being upset to present eyes f and brought togethersufficient to leave an opening f. Vithin this copper cylinder isretained the zinc element H by an interposed packing of felt G, the zincelement being cruciform in crosssection and its upper end extended andperforated for the reception of clasps or hooks h. By constructing thezinc plates as shown, a larger surface is obtained.

The copper element F, in addition to the vertical opening f, has aseries of perforations for the purpose of admitting the exciting-fluidto the absorbent-pad, and said cylinder is further left open at the topand bottom. The water-proof pockets prevent rapid evaporation of theliquid.

I11 making up a belt I prefer to use eight independent cells orbatteries, which can be connected or disconnected, so thatin practice Ican use any number of cells desired, according to the intensity of thecurrent required.

In the drawings, I refers to a conductor,

which extends from the zinc element of one of the cells to the copperelement of another cell, and K to a conductor which extends from thezinc element to the copper element of the cell adjacent. Theseconductors are insulated except at the point L, where they are bared andbrought in contact with each other and wrapped, thus practicallyconnecting two cells with two cells.

The construction of the electrodes and conducting-wires attached theretowill enable the current to be applied to differentportions of the body,and as said electrodes are flexibly connected to the cells the movementof the body or belt will not disturb the position of the electrodes.\Vhen it is desired to use only a few of the cells, the zinc elementscan be drawn out of the pads, so they will not be consumed by the acidor become inactive by the accumulation of scale or dead zinc thereon.

I am aware that prior to my invention electric belts have been used madeup of a series of cells, as shown in Patents No. 249,070, No. 328,829,and No. 2308,5 16, and I do not claim what is shown therein; but

\Vhat I claim as new, and desire to secure by Letters Patent, is

1. A cell for galvanic or electric belts made up of an outer casing ofcopper, the ends of which are bent to form eyes, a zinc elementcruciform in cross-section maintained centrally within the casing by aninterposed absorbent pad, the zinc element being extended above the padand copper element and perforated for the engagement with the books 7:of the conductors, substantially as set forth.

2. The combination, in an electric or galvanic belt, of a series ofcells constructed substantially as shown and connected to each other byconductors I and K, said conductors being electrically connected to eachother, substantially as set forth.

3. The eombination,in an electric belt having a case inclosing a seriesof cells, a slide 13, attached to the belt and having adj ustablyconnected thereto a plate B, carrying a loop 13 to which the cell-caseis secured, whereby the cell-case can be adjusted on a line with thebelt or below the same, substantially as set forth.

4. In combination with an electric belt, a slide 13, having headed pins11 a slotted plate B, retained by said pins and carrying aloop B havinga pin 1), for removably connecting the cell-case thereto, substantiallyas set forth.

5. In combination with a series of cells having an outer casing ofcopper, the ends being bent to form eyes f, an absorbent pad, as G, anda central zinc element II, having an extended end, conductors I and K,each provided at one end with hooks 7t for engagement with theperforations in the zinc ele ments and at the other end with loops F,the ends of which enter the eyes f in the copper element, together withconnections 0 and ,2, connected to the electrodes C and Z, substantiallyas set forth.

In testimony whereof I affix my signature in presence of two witnesses.
